I have the latest build 1.3.0.0002 , and when I attempt to decompose a weapon or armor and select it with my mouse to drag it to the decompose box the cursor changes to the item and never goes back to normal. It seems to lock out all ability to select anything including the decompose button. I can return to a normal cursor and exit the crafting menu only by using the keyboard hotkeys for inventory or character stats. Nothing else works. the rest of the game has been functioning normally as far as I can tell. I am still in the first section of the game so this is very frustrating. ANY Ideas would be of help.

Running win 10 pro, I7 3770K 4.2ghz , GTX 970, 16gb ram, 3TB HD , Closed loop liquid cooling, blah blah blah...

Solved the problem by reinstalling the game. Seems to be working fine now.

In case it happens again, switching to the alchemy tab and clicking on an item, then switching back to crafting seems to fix it.
