I'm using the -mt version of model viewer in the bin-mt folder and have experienced constant issues with the textures, args, and model drop down windows getting "frozen" and I can't select them. I can still move the model around just fine so it is like windows stop detecting mouse inputs. I also have problems closing windows and not being able to reopen them like the move object, liveries, connectors, etc. I can try to open them from the menu bar at the top but the window never appears. If I restart modelviewer with them checked they show up but will still freeze/crash the program.
Just wondering it this is a known issue or if my install is messed up.
