When I try to answer a call when I'm already in a call this pop up window come up. It askes me if I want to end the current call or place it on hold. It's especially annoying when I'm driving. Swiping the screen is already confirming I want to accept the call, why do I have to double confirm. The pop up box is so small and when I have my phone mounted it's hard to aim the selection.
See if adding -hold to the urxvt command helpsman urxvt wrote: -hold|+hold Turn on/off hold window after exit support. If enabled, urxvt will not immediately destroy its window when the program executed within it exits.
