Hmm.. It should work, try it couple times (you may do it from commahd window). Maybe you will need another numbers in MOVE WINDOW.

I guess that another approach would involve using 'custom' foxuser.dbf file. You can do following way: run your application, preview report, dock toolbar manually and then immediately save Foxuser.dbf/Fpt to some place. Now you may use this file in real run-time like this:
COPY FILE myfoxuser.dbf To dynamicfoxuser.dbf
COPY FILE myfoxuser.fpt To dynamicfoxuser.fpt
SET RESOURCE TO dynamicfoxuser
REPORT FORM myreport PREVIEW
SET RESOURCE TO
DELETE FILE dynamicfoxuser.dbf
DELETE FILE dynamicfoxuser.fpt

I have never used it, but it probably should work.
