[tommyboy]

i have just got the version of microstudio it works well accept when i try to close the program down it appears to have closed but is still running this makes impossible for other programs to access the sound card so i have to con\alt\del to close micro studio i am using 98 and have tried loading the software on another comp to see if it was a problem with only my comp but it does the same on that one the reason i need to close down microstudio down quick is because i want to access a music program without much delay a freind has an older version wich closes down properly is there anything i can do accept try and get an older version please advise
