--- Comment #2 from Austin Lund austin.lund@gmail.com 2011-02-28 18:56:32 CST --- I'm not entirely sure what to test for.
The only way I can see that the application can perform this feature is via the WM_LBTRACKPOINT message which wine seems to handle correctly when compared with windows.
I'm open for suggestions as to reasons why this might be happening and I'm willing to write the test case for such suggestions.
Unfortunately I don't have a binary to debug. However any suggested extra debugging channels that might help would be useful.
