MicroSoft word for Mac - 2008 Version 12.3.6 (130206) is to slow to react to selected actions. It takes too long to open and to save.
The Version 12.3.6 (130206) does not perform very well. It takes too long to open, close and save. My computer is an iMac 21.5 inch Mid 2014 1.4 GHz Intel Core i5 Processor with 8GB 1700 MHz DDR3 memory, so it is not an "old" machine! I think this version of Word is pretty feeble.
