Path/File Access Error again ... and I reckon I know what's causing it

I put this up while back, here it is again.

Im getting File/Path Access Errors whenever there is some intensive recurring file creation/closure/overwriting.

I can swear that what's happening is that my PC is soooo slow that a backlog of requests from QBasic is building up when this stuff runs.

make file
put stuff in file
close file
open file read data from file
close file
copy filename to another file name
go back and make next file


^^^^^^
i think it tries to open that file before the PC has acted on QB's request for it to make and close the file in the first place!

I seem to be able to fix this stuff with redundant file closure commands, and pauses to allow the computer to catch up. EG :

CLOSE #3
FOR CloseFrickenFile% = 1 TO 10000: NEXT CloseFrickenFile%
CLOSE #3

OPEN "formtrak.tmp" FOR OUTPUT AS #3


It still did it, but much less commonly, so I presumed I was on the right track.

So I did this instead :

CLOSE #3
FOR CloseFrickenFile% = 1 TO 10000: NEXT CloseFrickenFile%
CLOSE #3

FF$ = "Form"
FOR T% = 1 TO 4
FF% = INT(RND(1) * 10)
FF$ = FF$ + LTRIM$(RTRIM$(STR$(FF%)))
NEXT T%

FF$ = FF$ + ".tmp"

OPEN FF$ FOR OUTPUT AS #3
'OPEN "formtrak.tmp" FOR OUTPUT AS #3
FormInstancesFound% = 0




Well its all well and good to use that workaround, but its hardly robust.

Anyone else hit this trouble? Known what to do?
