Hi everyone, I'am a newbie
Something really annoying is happening to my form, one of
the subform keeps flickering, the only way to stop it is
running the mouse over it.

I tried "Refresh", "Recalc", but it doesn't work.

Does anyone know what causes this, and how to stop it.

Thanks in advance,
Emilio

One last thing, it only happens when there are many
items, say 5 or more
 
Hi Ken,

Thanks for your response.

No, there is no code related to the subform.

Thanks anyway,
Emilio
 
Hi Ken again,

No, it was a false alarm.
Something happened that seemed to solve the problem when
I deleted the clock and all the code and reseted the
timer to "0".
But I still have the problem.

Thanks,
Emilio

Is Conditional Formatting being used?
 
That is it!

The conditional was the problem, I tested and retested to
be sure.

Tha strange thing is that the database is 3 years old and
it has been that way since then, without this problem.

I would hate to live without conditional in that subform,
is it there anything that I can do to aliviate the
problem and continuing using it?

Thanks for any help.

Emilio,

Could you give an example of what you are doing when applying the
conditional formatting rule(s). Someone may be able to give you an
alternative of getting the same results?

Neil.

I've seen this before, but I don't have an easy solution for you.

What has changed since the time when you didn't have this problem?
Operating system, display driver, display settings, XP Themes,
recordsource query, table indexing, Timer event, volume of data ... ?
Those would all be things to look at. If you're running WinXP, I'd
especially try it with XP Themes turned off, because that's been
associated with some display-driver bugs.

Conditional formatting on a form, especially a continuous form, requires
an tight internal timing loop that continually passes through the values
on display and decides how the controls must be repainted. Anything
that slows down or interferes with that loop could cause the flickering.
One thing I've seen do this is the need to evaluate a user-defined
function for each record.
 
I am not sure exactly when it satrted in relation to
changes because I had motherboard problems in my notebook
and Toshiba changed the motherboard twice and god knows
how many things changed.
Anyway I decided to do whitout the condicional formating.

Thanks for your help anyway,
Emilio
