Survex Problems

[Matt Kirby]

Olly

Sorry I've only just got around to trying version 1.2.7a. I've attached a 
screenshot which demonstrates that the problems still exists. As before it 
is related to switching between programmes and I think the position of the 
cursor on the measure line sets the size of the rectangle which is created. 
However, this version does appear to correct itself if you switch programmes 
once more then back again. The screen redraws itself to whatever you had in 
the rectangle. This may be an improvement but it's not resolved the issue 
completely. What baffles me is why did our Mulu version of 1.1.12 work for a 
couple of years on various PCs then developed the problem out of the blue?

Is there any intention to include a terrain function in future releases, we 
have found it very useful for the Mulu stuff.

Cheers

Matt
