Hi Flowgun, no problem. Yes MoI v3 used an older interface for the file open dialog on Windows. MoI v4 was updated to use the latest.

re:

Do you still see the performance problems with v5?

There is also a setting in v5 to make it use the same Direct3D9 system graphics library that v3 did, you can set that in moi.ini under:
[View]
GraphicsAPI=Direct3D9

If you have a pretty old flaky video driver that worked better with MoI v3 that could make v5 behave more like v3 on your system possibly.
