SLOOOOWWW GLIDE TO 100% display in Bridge

I recently updated to the latest version of Bridge.

I select an image, press the spacebar to put the picture full frame on screen then press the left mouse key to enlarge to 100%. Before the update the image jumped directly to 100%, which is what I want it to do. Now it sloooowwwly glides up to 100%. How do I get it back to the previous behaviour ?

I don't seem to be able to find any setting in Bridge>Edit>Preferences which might do the job.

Any suggestions ?
