invalid cast exception

[pal]

Hi ,
 
First may I wish everyone a happy holiday .

I had a little time today so I tried to upgrade a project from 3.84 to 3.94 . The PLC is an AB Compact L32E
using IP for CLX driver . The status pages all went without a hitch but the last page has several basic buttons .
They use a tag for highlighting with the name PLCtoHMIbits.n and the click address as HMItoPLCbits.n .
    The screen slowed right down and some comms were lost . The exception  was located at line 1031 in the
ip for clx code . I have'nt done VB for nearly 20 years so I've a mountain to climb , and at the moment your code is beyond me .
Deleting all but one of the buttons restored normal function .
I'm wondering if this is associated with other problems you're having , and if this willl help solving it .

What is the highest bit number you are using?

At the moment , the highest is 7 . I did try adding a 2nd button but without sucess . Reviewing my previous post , I
didn@t make it clear that it was working fine in V3.84 .  I am at home now and don't have access to the program till Monday .
Thank you for your Quick response Archie , I didn't think anyone would be online till after the holidays . Please enjoy yours .

I was able to reproduce this problem with just 2 buttons. I fixed the problem so it will be part of the next release, hopefully within the next day or two.

Version 3.95 is now available that should fix this problem.

Hi Archie ,
I had to go in today on another job , but I tried V3.95 while I was there . Sucess !
Transfered from V3.84 and the pages all ran without a hitch . The 7 buttons all loaded
and worked correctly .

Thank you for your unexpected help over the holiday period .
