Indexer Halting Mysteriously (AREV Specific)

We have been running a dedicated indexing machine from a DOS workstation for some time now, and for reasons I won't get into here, are now using a Windows 95 workstation. Mysteriously, after processing just fine for some time, the workstation would stop processing indexes. After much experimentation we finally figured out what was causing the problem. We could cause the workstation to stop updating at will, seemingly without doing anything with Arev.
The application was running in a window (not full screen). As long as the mouse pointer was not over the window, the indexes were updated. However, as soon as the mouse pointer went over the window, indexing immediately ceased. In a normal situation, there would not be any mouse activity. However, if someone bumped the mouse, or if a Windows popup message was generated for some reason, this could cause the mouse cursor to appear over the Arev window.
It turns out there is a rather simple solution. If you edit the properties and click on the Misc. tab, there is a section for the mouse. One of these is called QuickEdit. When checked, Windows 95 allows you to copy DOS text without first going through the menu. A consequence of this is that mouse activity is not passed through to the application. It was this pass-through mouse functionality that was aborting the indexes.
OK. We have a solution, but what I'm wondering now is why does all indexing stop when the mouse is moved in Arev? Shouldn't it be like the keyboard and resume after the threshold time?
We are using HR-1 5.5 (Arev 3.02).

The thresholds and timouts only occur if nothing was passed in through the INPUT X,-1 commands in INPUT.CHAR. Perhaps, under 95 with these options set, something is being returned so there is no timeout and never idle, so no background process.
Just a guess….I should probably check it.

How did you setup your dedicated dos/win95 indexer? What type of trade offs did it give you?
