Hello Mishem and David,
I think I have found the problem. Mishem the way you use the zmSetMouseMonitor and zmDelMouseMonitor in the mouse enter and mouse exit is I think the solution.
Maybe the way you did it in your second sample would be even better.
I need some time to change a "lot" of things in my publication to be sure. After I have things running I will tell you the results.
Thanks a lot for so far and have a nice evening.
Regards,
Eric
