MouseMove( oMev) isn't called for a FixedText

[SUngemach]

The MouseMove callback is never called when the mouse moves over a FixedText

To Reproduce
Steps to reproduce the behavior:

1. Instantiate a Fixedtext
2. Write a MouseMove method with some debug code
3. Show the dialog
4. Move the mouse over the fixedtext
5. Check the debug console
6. Somethig should happen, but it doesn't ;)

Additional context
The modified assembly from Robert on January 30th 25 does the job.
