Error after exiting program

[stanks]

Hi

I have small gui example in linux (main window with hello world label in it) that gives me this error after i click system close button:

"
HLA Exception (54) at line 76 in ex_InstallSignals.hla, edx=$BFAFEA9C
Memory Access Violation
"

Any help how to solve it?

Thanks

I have found the error. Need to reread introduction to procedures  :red
