I can't help with getting the pane to show straight away, but I believe you can change the text in the LNG file. From within Robohelp (RH6, but I assume similar in RH8) go File > Project Settings, then click Advanced next to Language. The LNG File tab.
Thank you both for your responses. The developer is looking at the JS handler script to see if he can fix the window not openiing with the full layout. I also looked at the LNG file and see several lines where 'Show' is defined. If he can't get it to work we will try that way. I'll also see if I can figure out the Windows functions in creating new layouts, since it appears there might be some flexibility there.
Post back with the code changes if your developer does figure out what tweaks to get it launching "full". I bet there are others who are interested in seeing that effect too.
I had forgotten about the LNG tab settings - my people have been confused by the "Show" line too. I'm just playing with adjusting it & the mouse-over text that accompanies it.
