Description of Problem: stock-ticker applet wrecks vertical panel appearance bu increasing its size dramatically. create vertical panel. panel->applets->add->network->stock ticker panel expands widely. No options on preferences about honouring panel size. expected results: hmm. _ideally_ it should either scroll down, changing itself completely. Or it should scroll horizontally but not expand, even if this means you are going to see one or two letters at a time. Perhaps it should pick a very tiny font on a vertical panel if it did the latter?
I don't really think there is a good way to resize it. Maybe it should have a pref for how wide it should be. Anyway, could you report this to the gnome bugzilla instead? I certainly don't have time to fix this (low prio), but someone browsing gnome bugzilla might want to.
Okay it's now bug 59446 in gnome bugzilla. http://bugzilla.gnome.org/show_bug.cgi?id=59446
Ok. Closing this bug then.
