So i have spent 1 and half day trying to make one god damned cursed sig, that i so badly wanna finish.I had to start 3 times over and now 4.

this is my problem. the first 2 times Ps just stucked and didnt move anything.(i dont mind about that) BUT the other MAJOR problem is that everytime that i wanna press ctrl+t i press ctrl+somthing else (e,w,q,x,z,r) and it open me a window which says extract.first time it came out i clicked cancel and PS closed.This happened a couple times with other sigs but i really wanna know how to not lose my work.so i when i pressed the wrong button it appeared again.after cursing it i thought i should have a look to see if i could save it after all.but i dont know how to work it, i googled it aswell. it says something like " fill the areas that you wanna retain".i filled it and did whatever it told me but when i clicked on okay, PS closed again.

thanks in advance
