After the X2a install, the program opened and the whole thing is massive, like too big for the screen - like someone has fiddled with the screen resolution or something. I'm running at 1920 x 1080 using on board graphics on an i7 3770K under Win 7. Under the file, edit, view, etc drop downs, the boxes are normal size, but the general UI is completely stuffed. Any one else seeing this? Any ideas? 

No problem like that here...It looks like normal to me.

Looks normal here. Though the X2 GUI always seemed massive to me. Especially the mixer.

Thanks guys for the feedback, looks like something specific to me, just what I need, troubleshooting! I've never seen this before, what a pain, its unusable as is.

Could it have something with implementing the Windows Accessibility features? Check that in your Control Panel.

OK I've solved this. I had my Windows display preferences set to view at 150% which caused the X2a UI to blow out. Setting that back to 125% now has everything looking normal again. Interesting how X2 UI was fine at 150% anyway hope this helps someone else out! Thanks guys for trying to help.
