Unexpected Rapid Zooming #8

Closed peterallcdn closed 11 years ago

peterallcdn commented 11 years ago

Image zooming behaviour changes randomly.

Sometimes the image zooms as expected, with each step of the scroll wheel the image zooms a small amount.

Other times, the image zooms unexpectedly, where the image zooms quickly and zooms too far not respecting the steps of the scroll wheel. So with just a small move of the mouse wheel, an image can go from a small size to overflowing the screen. This makes it very hard to actually zoom to a desired size.

I've been using ImageZoom for a long time, and this behaviour has only started recently I believe... in the past couple months I'd say.

I'm running the latest version of firefox on Windows 8 and am using a Logitech Performance MX mouse.

Thanks for any help, Peter

Do you observe this behaviour consistently with the same image or can the behaviour be different with exactly the same image. I had observed this behaviour recently during testing but it was consistent and since I fixed the code I have not observed it. I will probably need your help to narrow down the scenarios under which this occurs as I cannot fix the issue if I cannot recreate it.

Thanks for the quick reply. I was going to do some testing to answer your questions and thought I should disable all my plugins first to make sure they didn't interfere... and, the zooming problem seems to have disappeared. I'm guessing there's a plugin conflict. I'll now enable them one by one and hopefully spot which plugin causes the problem with ImageZoom...

I didn't even know I had this plugin installed, but I should have known it'd be the problem the moment I saw it... Logitech SetPoint 6.5 "Smooth scrolling for Logitech mice."

Once the above plugin has been disabled, ImageZoom works as expected.

I will close this issue as I don't plan on doing anything to address the conflict with that plugin. thanks for reporting
