Hi

Is it correct, that if I have a DoubleBuffer display I cannot use MakeButton() to create zones for mouseevents? The regular eventhandler responds to mouse events (if set up to do so). But if I include a MakeButton statement, I am told that - 'A BGPIC needs to be active when calling button functions'.

In other words with a DoubleBuffer Display, as it is required by GLGALORE, i should read the mouse coordinates from regular mouse events and 'decode' my zones in the code?

Try using MakeButton() calls before calling BeginDoubleBuffer() and it should work fine.

This is actually a bug. I've fixed it now. Simply do as jalih says and create the button before starting double-buffer mode to workaround the issue.

Hi

Yes, executing the MakeButton() statement before setting up a DoubleBuffer works for me too. thanks. Since I experiment with multiple displays I just have to be careful that I have activated the right display for my MakeButton() statements..
