Error “Cannot change Visible in OnShow or OnHide” in Delphi IDE
问题 I have a very strange problem with the Delphi 2006 IDE. If the IDE is minimized, and the PC is locked. I return to the pc, unlock it and maximize the IDE, I sometimes get the error "Cannot change Visible in OnShow or OnHide". If this happens, I have to kill the IDE with the taskmanager. Is there anybody out there who has the same problem? And if possible a solution? I suspect that some third party components are involved, but my coworkers never experience this error. 回答1: Yes I have noticed
