I have noticed when I have my favourite radio station podcast loaded and I minimize the FF window to the taskbar the PC slows down? !!! url = http://www.rtbf.be/radio/liveradio/classic21 The PC is running WinXP SP3 +ALL updates and FireFox 37.0.1 The hardware is Asus P5Q Pro with an Intel E8500 Dual core CPU. Gfx = Ge Force 9700GT with the ver. 340.52 driver pack installed and 2 monitors attached. Mouse is Logitech with ver. 6.65 driver package installed. The scenario. I have MS Office Outlook and MS Word running + FF with a radio station playing. Radio is ON and the CPU load is 15-16% (window is on screen) now I click the Minimize button and the CPU load goes up ~ 10% to 26-28% and the PC slows down NOTICEABLY! Next scenario. I have MS Office Outlook and MS Word running + FF with my home page showing, CPU load is ~5% (normal). now I click the Minimize button and the CPU load goes DOWN to 2-3% (normal) Any ideas anyone? ??????.
