I notice that the TRIAL Adobe Acrobat DC interface has IRREGULARITIES when editing existing text. For example: I will try to put a space between two words but the result is negative space. The space bar acts as a delete key. Another time I'll have no trouble inserting a space. READER DC is NOT open repeat NOT open. I also notice there is no method of setting to DEFAULT the Font Type and size so that each time I edit one or more cells I have to change back to Garamond and set the size again at 13.92, ALTHOUGH I do see sometimes that the 13.92 is preserved. IRREGULARITIES as mentioned. Using the trial version for six days on an HP Pavilion DV 6 Notebook, Home Premium Windows 7.Service Pack 1 (build 7601).
