AV in rbRCL55.bpl using RB6.01 for D5E

I had RB5.56 under D5E, working pretty well

I have installed RB6.01 in normal manner, but now when I use the IDE to edit
my project, I get AV at 04D61CF2 in module 'rbRCL55.bpl'. Read of address
00000008

I can open my project and work pretty much as usual, but if I open a form
which contains my RB components, then Delphi generates the AV described
whenever I try to save the form. Clearly something is getting changed
(automatically) when the form is opened because the IDE asks if I wish to
save, even though I havent changed anything myself.

The same error (at the same address) happens whever I open any forms of a
similar style (involving RB components) within my application.

(I am using Waler TExtraDevices, but have installed latest RB6 version and
recompiled with RB6.01)
(I have checked C: drive for rb* components; it seems only files timestamp
6:01 are present.)

Can you suggest what may be occuring and what I should do to further
diagnose the cause

Thanks

    Due to pressures of work, I have uninstalled RB6.01, reinstalled RB5.56
    etc., and all appears to be broadly OK.

    But I would still like to know what is causing this fault, so that I can
    move on to RB6.x

    Thanks

    Sorry, to hear of your troubles. I'm talking to Roger Ash in a thread just
    above this one where he is encountering an AV on Win 98. What OS are you
    running? I can't reproduce it.

    When a report is opened in a newer version of RB, it is converted to the new
    format, but it isn't persistent until you explicitly save it back down to
    file or database.


    Cheers,

    Hi Jim

    I am running W2K pro SP1 with MDAC 2.6; I am going to put on W2KSP2 right
    now anyway.

    I was not able to reproduce the problems making a clean project, so it
    appears to do with my existing RB items. Currently I store the reports as
    RTM files.

    At runtime the application loads the template from file with a given
    filename.

    At design-time I :
    a) open the ReportBuilder designer, which has an 'empty' report in.
    b) load (from an RTM file)
    c) do my editing
    d) save to file
    e) Finally re-load my 'empty.rtm' file which is a completely empty report

    RB5.56 seems very happy with this arrangement.

    I do this so that I have no permanent RB elements in my Delphi application;
    later this whole mechanism will be SQL stored, but there are other issues
    that I must resolve.

    I did try to load this report and save under RB6.01 but perhaps I should
    have forced a change; however the datetime of the file was certainly
    changed.

    I have 2 TppReport components on my form, and both contain the 'empty'
    report at design-time. Could this be the problem? RB5.56 has no problem with
    this configuration.

    Since I have returned to 5.56 the urgency of a solution is now reduced.

    Thanks & regards
