Hi everyone,
Recently I encountered a weird issue on Windows Server 2012, when user
clicks on a Combo box to open it, it causes the application to crash, our
app uses a specific stylesheet, but removing that stylesheet didn't change
anything.
We are using Qt 4.8.3 (I tried with 4.8.5 but no difference)
and I didn't find anyone else (anyone who spoke about it on the internet)
having this issue :/
Here is the back trace of crash which stops in line 2563 of qcombobox.cpp
calling view()->scrollTo(view()->currentIndex(), ...)

Any idea what may be wrong here!?
Thanks in advance,
