Aces of the Deep crashes when sending contact report

[Janus]

Hello classic subsimmers,

I play an Aces of the Deep career in Dosbox 0.74; it is June 1941 and I stumbled into a convoy with northerly course on my return trip to St. Nazaire

This needs to be reported to BdU of course, but when the Contact Report option is pressed in the Radio menu the game sort of crashes and the intro is played again which can be skipped normally and I'm back in the main menu.

Is this a known issue to anyone and might a workaround be possible? Apart from not using the Contact report?

Now that I made it to June '41 I was hoping that BdU might finally order to shadow the convoy and form a Wolfpack...
