Problems with Logitech G5 mouse and DPI settings in CSS

Since I bought my new computer, I had been experiencing a strange problem when I was playing Counter Strike: Source.

I have the blue, 6 buttoned one, and I use the two extra buttons (button 4 and button 5) for binding keys to voice chat, and for the !give command for the Gun Game ( GG ) mod for that game, because I belong to the Aus. DOA clan for GG and have loved our server for over a year now.

When I would press the button 4 on the mouse (for voice chat) it would reset my DPI to the lowest setting, and only give me 3 options of DPI to choose from, instead of the normal 5. It was effectively blocking the DPI setting I had set in Setpoint, the software you get for the mouse. This was strange, because i could still use the buttons for voicechat and to !give a weapon... so not all the functionality had been removed. I could also still adjust the DPI setting with the two buttons provided to increase the DPI (but only on three settings instead of 5)

I have googled this problem on a number of occasions, with a number of different search strings, and never been able to find anything that matched the issues I was having.

coming upon this thread, with this rediculously simple search string ( " g5 logitech button 4 resets dpi "), I came upon this thread:

I found that turning off the Game Detection setting solved my entire problem with this game, so I offer this post up, to be referenced by search engines in the hope that it may help someone else!
