I installed a couple of simple Leviton motion detector switches each to control incandescent bulbs in closets off a bathroom. They work just swimmingly except for one problem: if the exhaust fan over the toilet is turned on - even briefly - one or both (usually both) of the closet fixtures will go into a "strobe" mode flashing on and off very quickly. To resolve the issue the manual switch must be turned off then back to auto for normal operation. I am assuming the fan is on the same circuit but I'm not there now to check that. Any ideas as to the cause and, more importantly, a fix?
