[Lazarus] Lazarus frozen on F1

Wed Feb 8 16:23:43 CET 2012

Hello,

I have a strange issue. I configured chm help and everything was fine
and nice and then I restarted my IDE and suddenly on pressing F1 my
IDE froze instead of bringing LHelp. And now it always does that even
after I restarted the computer =( The IDE remains frozen in this
syscall:
