--- Comment #11 from Daniel Jelinski djelinski1@gmail.com 2012-07-23 02:42:25 CDT --- A test case is great, but usually generic bugs without any specific applications tend to wait forever for someone to fix them. Consider adding this bug to appdb entries of applications you tested.
This bug is caused by incorrect messages sent on right click. Easy to see by comparing the output of "WINEDEBUG=+message wine WineTest.exe" with native comctl to the same output with builtin.
