Game freezes (on calculating research?)

[von Schmidt]

ToW v1.50B, the game consistently hangs after the US turn in the Autosave. The cursor freezes and the game does not respond. I've tried waiting for 10mins without change.
If I alt-tab to desktop and back, the screen turns black.

The last line on the (attached) ConsoleOut is "Calculating research..."

3 warnings in the consoleout:
"WARNING: fleet Fleet #95 (at node 27) wants to go to node 3 but there's no path
WARNING: fleet Fleet #96 (at node 27) wants to go to node 4 but there's no path
WARNING: fleet Fleet #97 (at node 27) wants to go to node 73 but there's no path"
However, if I change the location of the fleets to were they want to go (eg change fleet #95 from node 27 to node 3 in the fleet.csv)the message disappears but the game still hangs with the same last line in the log.
So that might be a red herring.

Hope this helps; let me know if anyone has any ideas how to fix it.

..and never mind. this is the issue described in a previous thread:

Same solution: just click the mouse button even though the pointer is frozen.
