Bug 2506: can't move hotlist, history, cookies windows off screen

These windows are based on the "tree" template, which does not have the wimp_WINDOW_NO_BOUNDS flag bit set (and there is no code to set it after creating the window). The attached patches OR the flag bit into each of the four template definitions that we have (de, en, fr, nl). The bug cropped up when the tree view code was replaced. It's my belief that this flag bit /should/ be in the templates - it's part of the fundamental window behaviour definitions, which is what RISC OS has templates for. Code should only be altering flag bits if they need to be altered back and forth dynamically, e.g. to grey icons out. I cannot see any reason why the ability to drag windows off screen would ever need to be altered dynamically. Please speak up if you believe differently! OTOH if the team agrees with me, then perhaps there should be another stage of moving this flag bit into all the window definitions. Again, please speak up! When applying these patches, please bear in mind that some of the files contain top bit set characters for the non-English languages, which may upset your text editor. The files in question are all textual. Dave
