Hello, I'm italian so sorry for my english.
I have created a desktop very simple with GXT 2.0 M3, but I have a bug in Firefox that in Ie6 I don't have.
I open a Window with setUrl command.
Minimazing it, when I click on the taskbar (than lunch win.show()) in ie6 open the window without restart my url to homepage corretly, in Firefox restart my url to homepage.
It appends only with external url (with a window with a gxt grid componet ecc) I don't have the problem.
I'm experiencing this issue and i've tried to confirm that it's a firefox limitation. I've created a small html with an iframe and a js code to hide and show it with display none and the url does not reload. I've attached the example html. Please check it out.
