Hyperlinks only clickable with "shift"

Hi !
just installed 5.0.18661.0 update.
When clicking hyperlinks within an email, nothing happens. If “shift-clicking”, then the link is opened, but always in a new internet explorer window (eg, if IE already running, then a new instance is created)
Never noticed this before…
* system is w8 x64
* default browser is FIREFOX
I browsed EM Client’s options, but found nothing relevant.
it’s a bit annoying… would make me feel like :confused:
Thnaks in advance for your support !

Hello,

eM Client uses IE to show and handle HTML, please try to reset IE (even if you are not using it as default web browser) and let me know if it helped.

best regards
Jan
