Cannot Center Preview in GMDL

Hello,
Thanx for GMDL. I am having an issue with the ver 0.5.08b. I can not get my map to center where i want it to. It seems in the preview and Download for the maps it is alwas a little off[to the righ, or left but never center]. I cannot get it to center the map where i want to download it from. I am trying to download Wharton St Forest in NJ no mater how I try and center the map it will not center in the preview no mater where I put it. I can zoom way out and select the tiles i want but then i have a map way bigger than I need.

Please help.

I am experiencing the same thing, i think thats the way it is for all.... It is way off from what i select but by slow adjusting it can get the work done. I don't know how the past version worked ? anyone? ( maybe that bug will be fixed soon.)
