[Lowfer] SPECTRAN PROBLEM

[EVP]

    I have a new HP dc7700 PC with "on board" sound card.  Spectran and 
Multipsk work fine with it.  However, the machine doesn't have a game 
port and when I installed another sound card with game port I ran into 
this problem: 

    Sound card and game port work fine but when I tried to run Spectran 
or Multipsk [I had forgotten about selecting the sound card] I got the 
familiar BSOD with a message about hardware failure and "program 
halted".  Can't get out of that state without restarting the computer.  
I removed the new sound card and all is well again.

    Question:

    Has anyone else experienced anything like this?  I am hoping that if 
I reinstall that card and use the Spectran "select sound card" function 
all will work again but because of the inconvenience of putting the new 
card in and out [my own fault with the way the PC is hidden under the 
desk] I had to repeat the old frustrating experience a second time. 

Any comments welcome,

Ed
