I have the following remark ( maybe usefull...)
May the cause of all these, (color flashes, abnormal change of colors etc)
was the fact that i have an image as a background (root window) ...
when i remove it, everything work ok. It seems that this strange behaviour
begins when forms have few sells to allocate ... I believe that the root of
the problem was that i displayed simultanously about 80 colors, but forms
couldn't allocate more than about 60. Am i wright ?? Is that the cause of
changing allready allocated colors (even FL_BLACK for example..)?
Finally a request:
It would be nice if there was a forms function to return the empty color
sells, so somebody who wants to allocate many colors, to know where to
stop, before all these happen...
Thanks a lot !!!
