Game lock after trebuchet bombards

Playing: Scenario Alliances, Byzantium, 10th turn.

Trebuchet unit selected. I pressed "G" and then Shift + "B".

The game entered an infinite loop with the bombard animation for the trebuchet, and has to be killed from the task windows.

Windows 98 SE with latest patches. C3C Ver 1.00.

Note: I was trying to reproduce a minor bug described somewhere on this forum that say that trebuchets can bombard anywhere on the map after pressing "g" and then "b". ( I added the shift looking for the actual effect ).

Can you provide a game save where this takes place?

This looks a lot like the Indecisive Worker Infinite Loop.

This must be more connected to the Infinite worker loop than to the 'Bombard Anywhere' cheat. I couldn't make the game crash in a test scenario I set up, so anyone with a good savegame that reproduces this bug, please upload it.

Apparently this is related to having Win98 SE installed. Could a few Win98 SE users please try to see if they can reproduce it. And of course if a few non-Win98 SE users can reproduce it too, please report that as well.
