[Qgis-user] Unable to load project

Hello Responders,
Thanks very much for your suggestions and comments. Very helpful.
I must say though that the last few comments have again underscored my
nervousness about changing anything that isn't completely broken.
Firstly, why are there two installation processes and what is the
purpose of each? This implies making a choice after learning about the
benefits and disadvantages of each. What are the criteria for choosing
one over the other? How long is the process of understanding the options?
Secondly, there seems to be no great consensus over the possibility (or
not) of conflicts between simultaneous installations. Again, this makes
me nervous.
Thirdly, why are some operators running two or three simultaneous
installations? Does this mean that the latest version is not adequate
for some tasks?
All these things give me pause and discourage me from wading in to
something that may have a lengthy learning curve and an unpredictable
outcome. In this case, the devil you know definitely seems to be a
worthy rule of thumb. At least, until it fails utterly.
In that regard, I discovered that at some point I had installed 2.8.1
and, remarkably, it would load my ostensibly corrupt configuration
file. I appear to be back in business.
However, this version still bogs down upon loading the various layers
but does not fail after the delay. There are about 100 layers, mostly
vector.
Anyway, not sure if this is particularly helpful but is my current
thinking on the upgrading process.
Thank you all again for your assistance…
Cheers . . . . . Spring Harrison
