[comp.sys.mac.comm] DAs won't open while using comm programs in System 7

Here's a problem that only happens to me in System 7 while using
communications programs.

When using either MacKermit 0.9(40) and a modem OR using NCSA Telnet 2.3
(with MacTCP 1.0.1), try selecting any item in the Apple Menu.  I get
a beep and nothing else.  Option-selecting a DA doesn't work, either.

Yet DAs work fine when chosen in the Finder or in other types
of programs (word processor, spreadsheet, etc.).  Even if the comm
program is still open in the background.

The end result is basically what happened when the DA Handler file was
missing under MultiFinder in System 6.  But this is System 7 (yes, it's
the release version), and it has no separate DA Handler file!

The problem occurs on an unnetworked 4-meg Mac Classic and different
networked 5-meg Mac IIcx's, and probably on other Macs as well.  Common
extensions on the tested systems are Moire 3.0 and Disinfectant INIT 2.4,
but the problem occurs even with all non-Apple extensions removed.
Increasing the RAM allocation to the comm program also doesn't help.

Can anyone confirm this ... or offer a solution?
