The version of DL that's currently in the Ruby standard library has a hard-coded limit of 10 callbacks.
According to this post from last summer, some fixes in WinClicker methods were contributed to Watir 1.5, to work around this problem: http://rubyforge.org/pipermail/wtr-general/2006-July/006828.html ..., but maybe your code is running into the same issue in some method that hasn't been patched? Or your winClicker.rb doesn't have those changes for some reason? Not sure. You can probably fix this yourself by adding a call to DL.remove_callback in the method (in the WinClicker class apparently) that is causing the problem. Once you are done using the callback, you just pass DL.remove_callback the name of the callback that has been defined: ====================== enum_windows_proc = DL.callback('IL') { |hwnd| found << hwnd 1 # continue enumeration until all windows have been processed } EnumWindows.call(enum_windows_proc, 0) # Enumerate all windows DL.remove_callback(enum_windows_proc) # Now remove the callback. ====================== Incidentally I have had to make use of #remove_callback in a Win32::GuiTest workalike I've been slowly putting together. I decided to try to use Ruby DL for everything, instead of Win32API + C extensions, so the heart of the library (the code to enumerate windows) depends on DL.callback and DL.remove_callback. :) So far #remove_callback has not given me any problems at all. Otherwise Mark's suggestion of reusing a single WinClicker object, instead of instantiating several, is worth trying.
