IE 7 and GoDiagram

Hi, I have just installed the official version of IE7 and am having problems with the Overview and zooming the main diagram. Basically, when I draw my rectangle on the overview the main diagram does not zoom, however, as soon as I click the main diagram then it zooms. The other problem is that it sometimes works and sometimes doesn’t work about 50/50. Anybody encountered a similar problem? Any solutions? works perfectly in IE6

That appears to be a bug in IE 7 regarding the caching of images. GoDiagram Web 2.5.2 incorporates a work-around for this problem.
