I read that LV 7 resolves hardware access for Windows XP. It seems to me that it's only (very) partially true.
In Port and Out Port in LV 7.0 work only if you use them only one time. For ex., a simple program that reads the keyboard buffer (X60) for displaying the code of the key, when included in a while loop blocks completely the PC: no more operation is possible and you must reset the computer. The same is obviously true also for other memory address (for ex. the input or output register of the parallel port). Any suggestion? It would be very important for my didactic applications (I am a teacher)
