Windows WE IDE keyboard lag

On large projects (lots of items on a webpage) running the IDE under win8.
They keyboard lags SO MUCH, it becomes almost impossible to type. I have to write code in notepad then cut and paste it into my project.
Also the CUT and PASTE CTRL-C etc you have to press at least 6 times to actually get it to copy/cut or paste.

XOJO is getting close to unusable in windows. Even moving an item in the IDE 1 piexel to the right can take 4-5 seconds each pixel on the top of the range macbook pro i7 with SSD.
