Hi Nikolay, i applied your patch to wine-1.7.13 and it triggers for me. When i
click on OK in open dialog, i immediately get following two lines:

err:scroll:EnableScrollBar flag mismatch
err:scroll:EnableScrollBar flag mismatch

PS: WinMerge 2.12.4 + I tested this on "older" wine, because i had this version
prepared from other testing.
