I have recently installed the Microsoft Office 2010 on my Windows 7 machine. Before this version I was using the Office 2003 which was at least working fast. Office 2010 does not gets hanged on my system but it does not work in a way as it should be. I have seen many kind of lagging while playing the games but first time I have noticed any such issue while typing the words in the MS PowerPoint 2010. Actually it types it properly but when I type bit faster then it response the my typing bit slower as word goes on typing for 4-5 seconds even after I have stopped typing it. This issue happens randomly, Mostly when I have opened any existing file from the load network. Can you guys tell me why PowerPoint works slow while user starts typing?
