I have some subs...
sub mainframe: paints the common parts on the page, return button, big captions...
sub mainwindow: paints the explicit part of the main page, two divs with a link each one
sub quieneswindow: paints the explicit part of the first subpage
sub autoformacionwindow: paints the explicit part of the second subpage

from "mainwindow", we go to "autoformacionwindow", and everything works, it prints "texto",
then, we return (using the javascript:history.back()) to the "mainwindow", then we go to "quieneswindow",
everything works fine, it prints the correct content, then, go back again, and finally, we re-enter "autoformacionwindow",
but this time, the wrong content is shown, it shows the "quieneswindow" instead the "autoformacionwindow"... :S

So, am I doing something wrong? (probably, my BASIC is a little forgotten, also is my english

) or could it be a little bug?

If it's a bug, I don't believe the bug belongs to RB. I copied and pasted your code and couldn't reproduce your error. My default browser is IE7. I then saved and published your code, linking to the code first with IE7 (again no problems), then with Firefox. Aha! Firefox shows the exact behavior you describe. Do you think this might be one of those javascript events that needs an If IE then do one thing, else do something else?

Don't use javascript:history.back() in Run BASIC. The state of your RB program in dependant upon the address in your address bar; by going back, you're undoing server-side information. If you need to return to the main part, make a link that tells your program to generate that.

This is right. Backing up to a previous page can have unpredictable results depending on what your program is doing. Use LINK to provide a way to go back.

thanks for all,

I used JS because I used an image (like a return button), is thera a way to do this with RB?
(using an image that acts like a link)

thanks again

EDITED by Wurlde: I've seen the answer of my last question here...
runbasic.proboards82.com/index.cgi?board=question&action=display&thread=1201607191

so, for now, it's all clear now...

thanks for all again and sorry for the inconveniences
