Find your tablet control panel and there should be a tab that says mouse with dropdown options that you can assign to your left click. Make sure its just a click.

On Windows it's a separate program, Mac it's in System Preferences near the bottom. This has happened to me several times recently. No idea why but the fix is easy enough.

I have an Intus 4 and lately my left click is a double click with my mouse. I have installed the driver agn and went to the setup with no result.

Any Idea???

Did it happen all of sudden? (after previously working ok?)
Did re-installing the driver not help? (this usually helps)

Something similar (not the same, I guess, though) happened to me once - but that was (probably) caused by my fault (wrong settings) while my PC maintenance. It actually appeared after I ´cleaned-up´ (with One-Click-Maintenance TuneUp utility) my PC. Not actually sure how this was possible, I would never ever expect that maintenance utilities would ever touch my wacom settings/utility files (?!) - however, after I had run ´recovering´ procedure (with Tune-Up, again), the problem had been resolved.

Sorry for not beeing of better help,
just trying to say there are some ´mystical´ things happening too, beyond Wacom driver/utilite, sometimes. Tracking your own last activity (just before the problem occured) might help, sometimes, perhaps.
