Been awhile since I have posted, but thought I would add my 2 cents worth. I, too, have the same problem. Ctlr+alt+shift+r does not bring up a browse window. I have just reinstalled SC4 and RH and patched to the last update. I have no mods, nor bats installed in my plugins folder, it's clean. I have tried with three different maps, Duluth MN, Minneapolis, MN and Des Moines, IA from the Mapsquad map pack here on the STEX. I have never been able to get this to work right. I can't be certain, but I thought it might be the map sizes. I took the Duluth map and resized it to 1025X1025, then tried again. No change. Any help would be appreciated. I have been playing with the same maps now for years. Thanks!
