That seems to have done the trick. I had to manually delete %appdata%\Helios and then reconfigure after reinstalling, but it least it remembered my registration details. Thanks.

No effect.
However, I just installed 9.8 instead of 8.22, created an empty .xsl file on my desktop, and it opens successfully (despite silly IE-style icon).
Something interesting -- with 9.8, I get the same blank document behaviour trying to open a .txt file on an external disk.
So I've uninstalled ...

Well then I got nothing, sorry. Did you restart after applicable changes?

Yes. Thsi has been going on for a while. I hoped upgrading to 8.22 wuld fix it, but it didn't.

Some possible gambles:
Upgrade to 9.8.0
Uninstall IE, if present. (That looks like an IE icon)
Poke around in the registry ...

Aha! Fine, all working now. Many thanks.

This is what I see: Running TextPad 8.22.0 (64 bit) on Windows 11 24H2 (Build 26100.3775)

I have Textpadassociateed with many things, including XSLT stylesheets (.xsl). In most cases when I double-click an associated document (e.g. a .txt file) it opens as expected, but for .xsl files it just opens Textpad with no document, like so:

The same thing happens if I right-click ...

Change the background color of "Selected text (no focus)" for your document classes. The default color works in the dark theme, but it needs tweaking a bit with a white background. We'll change the default to this in the next release:
Thanks. It seems I have to do it for each document class ...

Something I frequently do is search for a particular regex. With other editors the found text is usually highlighted clearly, but in Textpad it's highlighted in a pale gray while the Find dialog has focus, and I can't distinguish this from normal text. I have to click on the main window before it's ...

I used Textpad with a second monitor attached, and I moved the search dialog to the other screen to be able to see what I was doing more easily. Later when I tried to open the search dialog again it didn't appear, and it turns out that it was being displayed offscreen (on the now-disconnected second ...

The erratic cursor movement seems to be font-dependent. It works correctly with Courier New, for example, but not with other monospaced fonts, e.g. Consolas. It also works correctly with some proportionally spaced fonts, e.g. Arial. Arial and Courier New both have "complex scripts" support. It looks ...

I'm trying to prepare property files for internationalising a Java application, and I've noticed some issues with Textpad's UTF-8 support for right-to-left languages (Arabic, Hebrew).

The issues I'm seeing are:

1) A sequence of words is displayed left-to-right rather than right-to-left, even ...

let me have a guess - you are not using a bom, and the copyright char is the only non-ascii character in the file.

It might help to put a comment like /*äöüß*/ into the file (close to the beginning). There are some other characters, but essentially yes.

I don't want to fill my files ...

In Configure > Preferences > Document classes > Java, I have specified UTF-8 as the default character encoding. However, when I open a Java source file which includes non-ASCII characters such as the copyright sign © (\u00A9), Textpad shows this as the two-character sequence © (which is ...

Apologies for posting everything twice. It keeps giving me an error message when I press submit:
Couldn't get mail server response codes

which I thought might be due to square brackets in my test program and output, so I tried again with parentheses... it ...

Ah. I just tried it with CMD (not a shell I normally use). I see what you see now. But this works:
"C:\Program Files\Textpad 8\textpad.exe" x.txt
So it's a CMD bug. Who'd've thought? Is isn't a CMD bug? I normally use 4NT or TCMD, and they do the same thing.

I wrote a little C program to test ...
