dhtmlxWindows - viewport doesn't let me use the underlying l

I am using dhtmlxWindows with the viewport set to the whole browser window by default.

In IE7 I can click on links in the document and the wanted dhtmlxWindow opens. In FF2.0.13 and Opera9.26 I can’t click on any of the links.

Additionally, in IE7 the viewport is to small by default if the content of the document does not fill out the whole screen.

Please try to use attached version of dhtmlxwindow instead of original one - it contain some fixes related to the way how default viewport works.
If problem still occurs for you - please provide any kind of sample where problem can be reconstructed ( you can send it directly to support@dhtmlx.com )
