Hey,

Whenever I try to copy, paste, or any other operation that uses the clipboard in the Propeller Tool, I get an error that says "Cannot open clipboard". I am using Windows 7 Ultimate.

    Using Windows XP & Vista works fine. I suspect nothing can be copied to the clipboard, so try copying some lines from Notepad. If this fails, google to try and find a solution.

    You might also try to copy / paste to / from notepad, out of the PropTool. I've done a copy paste in Win 7, and it works fine. Have you got the latest Prop Tool release? Have you made user account adjustments? Rebooted? Are running something else that might inhibit that operation? Try running Prop Tool in compatability mode?

    I have this error from time to time but not always.
    It makes a difference if a copy all text or some lines. I made some experiments but I did not find a regular pattern when in occurs

    try to mark and copy some lines, a single line, a single word.

    best regards

    Stefan

    I have experienced this also using XP-Pro Svc Pack 3. Most times reloading the Prop tool does not resolve the issue and Windows reboot is required. I swear MS has figured out a way to make money on every reboot.

    [Possible workaround...]

    Just seen this for the first time on my Win 7 Pro (SP1) and I'm an Administrator on the PC.

    In the code window, Ctrl+A, Ctrl+C always causes this error for code that is longer than about a screen's worth of text. Shorter than this doesn't seem to cause the problem, perhaps a buffer is overflowing in the Prop tool's clipboard handling functions.

    That said, the code does seem to make it into the clipboard (for me), I can paste it out into notepad without any missing text.

    This bug is a pain in the butt though.

    Further investigation...

    Deselect everything in the code window and then task switch to some other app, then go back to the Prop tool again and do Ctrl+A, Ctrl+C to copy the whole file to the clipboard... for me that seems to work without crashing. Doing Ctrl+A, Ctrl+C......Ctrl+A, Ctrl+C....Ctrl+A, Ctrl+C in a row repeatedly will soon cause the problem to reappear. Task switching away and back seems to get around it on my machine.

    [Rampant Speculation...]
    If the Prop tool is using some windows API calls to perform the copying, then perhaps some handle or pointer is out of date. The task switching workaround might suggest this.
