This one has got me stumped: When selecting a custom menu item with data on the clipboard the GUI freezes. Freezes are longer for more data and longer for older versions of Labview. I wrote the test code, attached, but the example "Menu Selection Demo.vi" shows the same behavior. Running Labview 2011 here are some freeze delays for my laptop (a bit slower machine) with various amounts of text data on the clipboard: Clipboard size Delay 1.3MB 2.1 sec 2.6MB 4.9 sec 3.8MB 17.2 sec 14MB 253.3 sec The delay appears to be non-linear. A doubling of the clipboard data size more than doubles the delay and a tripling of the clipboard data size produces a delay of almost 10X! Things are also much, much worse on my ancient version 8.2.1 (over a 40 second freeze for 1.3MB and it goes up from there). Note that the freeze also occurs on programs with a custom menu when exiting. This would seem to suggest it might have something to do with the timeout, but why timeout should vary with clipboard size and not with the value wired to it makes this feel even more like a bug in the custom menu functionality. This seems to be related to known issues in Labview 2011 #39604 49UBP4LE (http://www.ni.com/white-paper/13168/en#39604_by_Date) that was first reported in version 8.2.1. This known issue relates to Labview freezing when large amounts of data are copied from Labview to the clipboard. No fix has been implemented since this was originally reported in 2007. This freeze also occurs when shortcuts to menu items (such as Ctrl + L) are used when large amounts of data are on the clip board. Thus far this has been 100% repeatable and I have not been able to find a way around it. I also haven't found anything else similar on the forums or on the web. It appears to be a GUI freeze with Labview still running in the background, which is also odd. My work-arounds at this point are either to not use the clipboard (bad), programatically clear the clipboard several times each second (worse) or remove all custom menu functionality and replace those functions with onscreen controls. So, for now, I'm removing custom menu items because my users need the clipboard and I can't have massive delays making my data acquisition code look crashed. Any ideas would be helpful. This one has me scratching my head...
