So I'm developing my game on a low end pc, and I've had no issues so far except for this. Everytime I make a keyboard shortcut, such as CTRL+Z or something as simple as pressing "DEL", they never do anything on the first attempt and hardly ever work. This worked on my decent-ish pc, but for some reason it doesn't on my low end pc. Sometimes I have to use point and click options, and some times, for some reason I have no clue why, the option is locked. (look at attached image) Is there a way to fix this? Sometimes it can get REALLY annoying and frustrating. Here are my requeriments: Code: OS: Windows 7 Professional SP1 (32 bit) Processor: Intel(R) Atom(TM) CPU N2600 @ 1.60GHz 1,60 GHz RAM: 2,00 GB Maximum Resolution: 1024x600 Oh, I don't know if my computer is over or under the minimum requeriments, but before you say it's not, the rest of the engine works perfectly, it's just keyboard shortcuts on the sprite editor. EDIT: It seems like it's not just the sprite editor, but today I noticed I'm having this same issue on other stuff too, such as deleting sprites. EDIT 2: Ok this seems further than keyboard shortcuts. Sometimes, Game Maker will freak out and won't let me work on anything. Opening objects, rooms, etc only make my mouse go "loading" and open nothing at all. If I try to close GM, the "do you want to save" window shows up, but it does'nt do anything after that. This is only after a while of using it though, generally it works ok.
