UISlider web / pc version click goes wild

[SheepIt]

Im using version 2.7.

The slider works great for the tablet version, but if I click on It to set a value , its like the "up" of my click is never recognized, it will jump wildly until I click somewhere else...

NGUI 2 cycle has been deprecated and is no longer officially supported. I would suggest trying it in the latest of the NGUI 3 cycle (which is currently 3.0.7 f3).

I dont want to do this, because it probably will need lots of changes on my part.
Any hints anyway what it might be?

I've upgraded a very old project from NGUI 2.2 to 2.7 and then to latest in about 20 minutes. Since you're on 2.7 it's probably even less work so I'd suggest giving it a try. If it doesn't work just revert the changes. Aren's upgrade tool works great. Make sure to follow the upgrade instructions and drag your prefabs into a scene and run the upgrade script.
