canon XSI flash problem?

whenever i half press the trigger, the flash goes off like crazy, lighting up like 3 times. does this happen to anyone else?

What you are experiencing is a normal phenomenon. When the light levels are low, your camera will try to use the flash as an autofocus assist. Get an external flash like the 430EX II or 580EX II if you want an IR autofocus assist. (IR AF assist is much less annoying for your subjects then the flash burst used by the pop-up flash.) If your end shots won’t use flash, you can get the ST-E2 for autofocus assist without using a flash.
