ProE DWG export (II) - ACAD mangles dimension text?

Hello again,
using the trial-and-error method we recently found out
that exported DWG files become _monochrome_ (grey)
when exported via a mapkey... when done manually and
step-by-step the colors stay alive, something important
for ACAD since line thickness is coded via colors there...
To exclude the possibility of an error of ours we wrote the
mapkey again (and again): same effect. Colors vanish.
Isn´t this strange?
Yet not solved is the problem of how to rescue the text in
dimensions, with tolerances etc - which is heavily mangled
by ACAD on any modify attempts. Even a move rotates,
resizes etc. (see former posting).
ProE is 2000i2 (problem seems to exist in all versions).
Any help still greatly appreciated!
TIA
Walther
