Summary 0003323: Programm crash/freeze with a blinking JvLED and application minimized !!!
Description The JVLED component has a bug, that generate an GDI object for every blinking, but not free it. So that for every blinking the GDI objects add up. The GDI Windows2000/XP limit is 9999, so crash the application after aprox. 9999 blinkings :(
This behavior is only, when the application is MINIMIZED! You can see it easily in the task manager, when you activate the GDI object column.

1. Application is NORMAL, GDI object count stand still
2. Application is MINIMIZED, GDI object increase
3. -Application is NORMAL again, GDI object count still stand again

see the uploaded file for an example.

please fix it and send me an email (, so that I can use the blinking feature again.

Fixed in CVS. This is actually a VCL bug. I have added a work around for JvLED.pas.
