    Don't know about the MC68705, but, I had this exact same problem with the
Xilinx XC7336 CPLD with the window....if the window was open, it would not
program correctly and would behave very strangely...so I would take this
suggestion below very seriously....and it is funny, I have never had ths
problem with just plain eproms....but all I can say is thank you to the silicon
gods for flash memory....
