[Xymon] issues with zoom-in (with some browsers!)

[Soporte Infraestructura Operativa y Almacenamiento]

Hi everybody:

I'm dealing with an issue with the zoom in on graphics generated by xymon 4.2.3.
AFAIK the issue appears "sometimes" on FF3X, FF4X and Opera 11.x but not on IE8, Chrome, Safari, Lunascape6 (no matter which engine I use).
The problem is that after hit the zoom-in icon the page is correctly rendered but the zoom-ing area is covered with a blue rectangle. So you can't see the zoom-ing data although the scale is modified.

I have attached a screenshot of the issue. To make things worst this issue sometime happens and dissapear after sometime (range time vary).
Does anybody suffer this problem? can be a problem with the WebUI?

Thanks a lot for anyhelp.
