I have assumed this is a graphics issue. I have a K2000 card and get this. Sometimes I have to take the mouse on and off a couple of times to get the screen to switch. It feels like MS changed the graphics from win8 onward and SW have not yet got it working properly (only 3 years...). I am currently downloading a new graphics driver every other week. Will be upgrading to win10 once SW2016 is stable to use... maybe that will cure all issues
Thanks for your reply Alex - So, I'm not crazy :-)
It seems to be a 'windows vs solidworks' issue - I've had it on multiple PC's, OS' and SWKS versions.
The only TIP I can offer myself is make sure each solidworks window is rebuilt before minimising the whole solidworks window.
Also use 'show desktop' (tag on RH end of task bar, bottom RH corner of windows7) WITH CARE as it also can minimise the whole solidworks window.
Any more tips to avoid this irritant ?
