bug with VST~ read message

hi

for years (on MaxMSP 4.x) i was using a write message to store prestes to my plugings

the form of the message was

[write Deep:/Users/KTT/MAX_Ongaku/PLUGSfx/frtest]

(DEEP being my HD, KTT my user folder etc, and frtest, in this case the name of the preset i am wiling to save in my PLUGSfx folder)

to reload this preset I was of course using the

[read Deep:/Users/KTT/MAX_Ongaku/PLUGSfx/frtest]

message

now that i have max 5, I am stil able to write teh preset file (I can see it) but NOT to read it - it says
it can't find it......

if i write it with the .fxb suffix, it gives error-1

how can you save and reopen plug-ins presets automatically??

_since i am currently giving giving a workshop, i was able to test it on many machines, macs, various OSX and max versions - 4.X works, not max5

thanks
