Unable to Sleep When Using Mouse

Clicking on a bed brings up the PDA with the Sleep Timer screen. Selecting "Set" with the mouse button causes the PDA to lower and the camera to zoom in on the bed, but nothing else happens. The only keys that cause a response are E - which brings up the PDA as normal, after which the PDA can be lowered and the game resumes functioning as if I had not tried to sleep - and Esc, which brings the PDA back into view, but only halfway. However, it also frees camera movement and WASD motion, and pressing E lowers the PDA as normal.

Using Space or Enter to select "Set", however, results in the expected fade-to-black, saving, and waking up after the set period of in-game time. The problem only occurs for me when using the mouse to select the "Set" button.
