VB: After adding modules menu navigation slows way down

 Repro'd on two Winxp machines (will ask MC to test Vista)

1. Launch VB with no modules
2. Navigate the status bar menu structure, it should be fast and responsive
3. Add LCD module to any slot

Actual Results: Status bar navigation slows way down when delving into the menu
Expected Results: Status bar navigation is fast when delving into the menu

I was unable to reproduce this on my XP environment, but Brian C is still

The stream multiplexer reads from inputstream, and if -1 is passed continues to
try to read.  In VB a sample file is used to simulate hardware, but then after
awhile the file data is exhaused.  -1 is always returned from read() at this
point resulting in an infinite loop condition.  There is a built-in 'read
delay', the fix was to use the appropriate constructor to set the read delay to
a sane value.
