I am receiving some errors when using the GUI classes and I'm not sure why they are occurring. I would be grateful if someone could suggest a reason for them. The first one occurs when I close down a window inheriting from TGTransientWindow Error in <RootX11ErrorHandler>:BadWindow(invalid Window parameter)(XID: .....) I have attached the code for this window. The second error occurs when I select a pad within an TRootEmbeddedCanvas (by clicking with the middle mouse button). However it only occurs after I have opened and closed another TGTransientWindow which also contains an embedded canvas. Error in <RootX11ErrorHandler>:BadDrawable(invalid pixmap or Window parameter)(XID: .....) The same histogram is present on both canvases, though one was drawn with DrawCopy(), I wondered if this could have an effect, though I don't see why. If anyone could offer any suggestions I would be most grateful. -- Colin Partridge stack@lineone.net http://website.lineone.net/~stack/
