It looks like there really is a bug, I reported it to PCSOFT and they passed it to developers. Question is how to create some workaround, when user clicks on it nothing should happen in "Creating a pane" or "Closing a pane" events. I have following code in "Creating a pane in TAB_Version" event. Testing if TAB_Version is grayed works fine and my procedure NewPane() is not run BUT new pane is created anyway in the moment when program leaves this event. I tried to use _EVE.Return = 0 which works for me in some other situations but not in this one. [code:wl] IF TAB_Version..grayed = false THEN NewPane() _EVE.Return = 0 [/code] I would like to use some solution also in other situations not only in this one so I hope somebody will help. I will appreciate any hint.
