PSX Emulator - Freezing problem

Emulator - PSX
Game - Monster Rancher 2(using physical disk)
Issue - Whenever I need to swap the discs in the game, PSX will freeze up and refuse to work for me. It says that 'it can't respond' and I need to shut down. Does anyone know the issue I am having?

I suggest try using other emulators, such as ePSXe.

I tried that, but when I try to change the disc, the game still recognizes Monster Rancher 2 as being in the disc drive.
