I tried opening a map, and after many tries it worked(without any problems).
Now though, 2.6 is glitching up like friggin' hell. It's switching itself to bold, lower resolution text sometimes, if I try to open using the taskbar icon at the bottom right of my screen it says that it performed an illegal operation when it finishes loading, when I try to save as .chk is saves as Map name instead of map name.chk, the mini-map view box at the top left will leave white lines wherever I move it, it uses the wrong characters in some places like instead of arrows it has 5 and 6, though cut off partially due to lack of space, I can't save maps as... please note that all the problems seem to occur randomly, but there's always atleast one of them occuring when I open it.
It's getting extremely frustrating. How do I fix this?

EDIT:
And I'm sure I forgot some. Here are 2 more problems: New one, when I open the trigger window, then it'll show the wrong groups(forces, players) at the top where you select it, and I have to click and drag to see which one is force so and so 'cause scrolling won't change it, graphicaly. ALSO, when I try to modify a trigger, a big purple spot(I chose purple for my 3-d buttons and borders colors under properties, appearance) and then dissappear after a second.
EDIT again:
Okay, it's not a problem with SCXE. IT's a problem with SE! If anyone wants the map that caused this problem, I can give it to you through e-mail. But I'd advise you not try to open it obviously lol. Something is SERIOUSLY wrong with that map, because it totally effed up my SE, and thus SCXE. Though, if anyone would like to see the map and try to find out what's wrong with it, be my guest. How I know it's SE, not SCXE:
SE is messed up too.
I reinstalled SCXE, and it didn't do crap.
