Mouse buttons 4 and 5 open edit dialogue for marker names instead of executing shortcuts

I have bound a few shortcut commands to my mouse buttons using a hotkey program. Before one of the more recent updates to Audition, I had no problems using this method. Now, however, I cannot click the mouse 4 or 5 button without the most-recently-edited marker name window opening for edit. Is there any workaround for this? It's driving me nuts and seriously affecting my workflow.
