My 7" Tablet PV210 Samsung CPU SA8, Android 2.2, Flash 10 1GHz,512 RAM,4GB Flash,Capacitive multi-touch HDMI,Meta came with Documents to Go 2.003 (605) and the Key. I have a problem and was wondering if others are having the same problem. I'm opening up an Excel file with sheets to go. I've formatted the cell to a different color and saved the file. When I reopen the file the cell has reverted back to the original color. I can make changes to the text, saved, reopened and the new text was still there. It seems I just have issues with changing the color of the cells. Anyone else run into this and where you able to correct it?
