Image Handler 4 (for v1.5.x) Support Thread

[Hasher]

Hi All

Installed IHv4 and only have 1 problem . On the product screen when I hover over the thumbnail I get image appearing. But when I click on the the thumbnail a popup window appears but the window is minimized to a really small size. once i manually size up the popup window i can see the image.

How can i set the pop up screen size ? I included a picture to show the problem.

Thanks Paul
