On my desktop, i use exclusively, my graphic tablet instead of a mouse. I don't have a mouse connected.

A few weeks ago, i realized that i could not play some videos that were stored on Amazon S3. Thinking it was the videos themselves, i tried to play other videos that were embedded on my site. They would not start (but they play on YouTube though).

I tried these:

- changing browser (Chrome and Firefox): didn't work
- playing the videos from my own computer: didn't work
- reinstalling the latest driver of the tablet: didn't work
- rebooted the computer: didn't work

Finally, to test my hypothesis, i connected a regular mouse instead, and that works as it should.
I contacted the company, in case there was a recent conflict with possibly a Windows update, but they have nothing like that on record. They suggested to log in on a different account to see. I did that, and the tablet works fine on that account.

So now, i am a bit at loss to figure out what is going on and what to do to fix the issue.

I am using Windows 7, Professional and a Wacom Bamboo Fun.

Any suggestion would be welcome.
