Interestingly enough, I can't reproduce the behavior you get running on my machine. See my response to Bruce for the behavior I see. I take it from what you describe that there's not a single thread for executing window actions so they are forced to execute sequentially > Feel free to contribute improvements to the C code for handling window > resizes.

I have a feeling that this is non-trivial, as I expect it does mean rewriting the window code so low-level window actions are performed sequentially. Given that I haven't written any meaningful C code in over 25 years, I'm pretty sure I'm the wrong person to tackle this! Incidentally, I've modified the original code (named by the author as 'rosetta_clock.icn' as he wrote it for the RosettaCode site) to get around the problem I was having. After resizing, if the window isn't square, then a simple mouse click in the window will square it up. -Steve -- Steve Wampler -- swamp...@noao.edu The gods that smiled on your birth are now laughing out loud. ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
