Cursor Lags, On Maple Only.

Hey guys its been happening a few days now and i can't maple with this lag. I googled and researched online with similar conflict, apparently nobody has this problem besides me. I cannot reformat pc because of a few reasons(hard to explain) and is low on budget for a new pc. With a limited computer software knowledge, I'm desperately seeking for help/advices/solutions asap to amend this problem.


Problem:
-Maple lags when ever i move the cursor.
-(Only) happens on maple// Web Browsing // Video Streaming// is completely normal.
-Moving the character there is no lag, only when moving mouse.


Applied Possible Solutions(but still lags):
-Replaced new mouse
-Reinstalled Maple
-No virus
-Plenty of free GB
-Good graphics card
-Set'd Maplestory under high priority on tskmanager.
-Set'd BlackCipher.aes under low priority on taskmanager.
