Weird drawing opening issue

Hello:

I'm using the latest version of DraftSight Pro. I'm having a weird problem that was never an issue until the latest release. Here's the scenario:

DraftSight is running with one drawing open. I'll refer to this as DRAWING A.

Often, rather than using File, Open in DraftSight to open another drawing (DRAWING B, etc.), I go into Windows Explorer where the folder containing my drawings is & open the drawing by picking it in Explorer. This ALWAYS worked in older versions of DraftSight. I'm sure many users do this exact same thing.

Here's the weird thing that happens: DRAWING B will NOT open unless I return to DRAWING A & select File, Save As & overwrite DRAWING A. As soon as I do this, DRAWING B opens!

Is anyone else having this problem? How can I fix it?

Thanks
