How to change the height and width of a text-only popup

[_PE_]

Hi folks,
is anyone out there, who knows how to do it?? We are using the text-only popups for explaining abbreviations in our topics. Using the properties to change horizontal or vertical ranges only applies to the margins of the text within the popup. In the generated WebHelp the text popup appears always in a fixed width and height and is in most cases too large. We are using Robohelp X5 and the generated WebHelp is running in a Mozilla browser on a Solaris system, so autosize does not work and that is the real problem.
The Comilier/generate option for DHTML is set to no applet and pure HTML.
Any idea is appreciated,
regards, Petra

Hi Petra and welcome to the RH community. They should be autosizing and certainly are in other browsers so I think this may be a browser / platform issue.
