WIN500/Pro-106 trunking problem

I am having a peculiar problem with WIN500 and my Pro-106. I have a trunked system programmed (Bucks County, PA.) The scanner is not showing the T indicator on the screen when scanning and I am not receiving any transmissions. However, if I enable Monitor/Control in WIN500, I can receive transmissions fine and the T symbol shows on the screen. As soon as I turn off Monitor/Control in WIN500 the T symbol disappears from the Pro-106 and I cannot receive the trunk system. Any ideas? Thanks.



P.S. I have other trunked systems programmed that do not exibit this problem.
