Use No Z-order Grouping (-nozgrouping) to disable the grouping of ABL windows at startup.

Client Session — — — —

By default, the AVM groups all ABL windows created in a session such that when an ABL window is brought to the foreground all other ABL windows move to the foreground with it. This startup parameter can be used to disable grouping. Grouping is automatically disabled when an application displays a .NET form.

Grouping can also be disabled by adding the NoZGrouping=yes setting in the Startup section of the Windows registry or progress.ini file. See Manage ABL Applications for more information.
