I recompiled an existing application from D2007 in D2009. And now I'm testing the applicatin and sofar it seems that my current dbexpress driver 4.20.04 works fine ( still tagged 'core lab' )
Am I 'lucky' or are there any caveats

( PS I'm not using unicode character sets in the DB. All .dll are only in my application path so I'm pretty sure it is not using the trail driver for D2009 that i also had installed -- I removed the dll from system32 -- )
