I have a Microsoft Trackball Explorer configured propertly, so that every button works as it should (through XF86config) and now I try assigning ALT+left to one button and ALT+right to another using this .imwheelrc:
None, Left, Alt_L|Left
None, Right, Alt_L|Right
Everything works perfectly (like back and forward in Konqueror) but when it comes to Firebird, which used to work well before imwheel changes, now it acts as page down and page up (pressing ALT+left or ALT+right using keyboard still works as it should).
That's very strange but I don't know what to do!
