Hi friends:

I have a few systems working in VFP 9.0 and there are not many problems

But...

From time to time an inexplicable error appears.

I mention this for example only:

At start I create an object named "oentorno" where I save "SETs" for restoring them before finish the system.

Suddenly an instruction as "SELECT CCOSTOS" (a cursor) provokes an error.

There's not a logical (for my humble level) reason for that error.

Error events executes and tries to open a table to register the error.

When I open every table I use a routine (in a PRG file) having this instruction:

USE (OENTORNO.AENTORNO(17)+'FILES') IN 0

Another error appears:

"Object OENTORNO not found"

I know there are many experts among you, friends. Please remember when you were babys (as me) programing perhaps you encountered this kind of errors and you can explain me

I must say the 99% of times error events works well, I find the reason and I fix it up.

But I'm really upset when I can't tell my clients: "I've made a mistake" because the same program I executes n times at n+x explodes..

I thank you very much in advance for your time.
