GuiSetStyle, Remove styles

[ranukano]

local $guiStyleoriginal = BitOR($WS_EX_TOPMOST, $WS_EX_TOOLWINDOW)
                    local $guiStyleremove = BitNOT($WS_POPUPWINDOW))
                    GUISetStyle(BitXor($guiStyleoriginal, $guiStyleremove))

The GUI is originally set with Topmost and Toolwindow. I then have it set with static positioning to remove the programs title bar which applies PopupWindow on top of Topmost and Toolwindow.

That works. However when I try to return it to just Topmost and Toolwindow it seems I fail. I've tried numerous ways and read multiple comments, the examples, and the wiki. I'm afraid I've only confused myself and now I'm not sure how to apply this.

Though, it could also be that once i apply this style, I'm unable to remove it without restarting.

That one was a real bugger ...
