Pressure sensitivity strokes are very thin ...

well at least we can both have it working...

for a couple of years or so pressure sensitivity in inkscape did not work with wacom on windows [python library issue]a nuisance, as if you want shapes drawn as lines, the inkscape calligraphy tool is very useful

Agree!

But Coreldraw and Adobe have good drawing tools for tablet drawer too.
In AI is a tool that is near to Xaras Shape Painter Tool caled The Blob Brush tool.

In Coreldraw is a calligraphy brush as vectordrawing tool to.

Inkscape in the latest version, is an awsome free vectror drawing piece of software and some functions are light years ahead compared to Xara.

So; it was the WinTAB after all. Just came home and installed a WinTAB driver (the first one I could get hold on. For anyone in the future having the same issues: look for gqgt01ww.exe. You'll find copies all over the Internet)
After the restart of Windows 11 fired up Xara Designer and, lo and behold, finally a working pressure pen again!

Thanks a lot for you all. And kudo's for Handrawn, for he nailed it!
