[R] DCOM - RODBC/RMySQL problem

I have a windows application in which data are written to MySQL and R analysis initiated by a VB frontend. After upgrading to DCOM 1.35, the analysis has become excruciatingly slow when processing a simple RODBC query. I am using DCOM 1.35 - I didn't have this difficulty prior to upgrading. I upgraded all other associated software with no change in performance: R 2.1
MySQL 4.1.10
MyODBC 3.51.11

I then installed DBI and RMySQL. I have been working with RMySQL using emacs. When establishing a connection, Rterm crashes with the error "instruction at "0x78001d0b" referenced memory at "0x00000000" the memory could not be read."

Is anyone familiar with these problems? Any help is appreciated.
