4229.0. "Jittery MuchMore V2.7" by HKFINN::MACDONALD (VAXELN - Realtime Software Pubs) Sun Oct 28 1990 10:21

    V2.7 of MuchMore has been released. Along with it is a version that
    will also read text files packed with PowerPacker. Yesterday I upgraded
    from V2.5 to V2.7 but discover that the smooth scroll is now quite
    jittery. Has anyone else experienced this with V2.7?

4229.1Works fine for meDECWET::DAVISYou always get what you deserveSun Nov 04 1990 19:273
    V2.7 works great for me.  I cannot tell the difference between v2.5 and
    v2.7.

    Now the question is what makes V2.7 jittery on my display but not
    yours. And, why is 2.5 just fine on my machine.

    I am using V2.7 and notice that only the 1st screenfull of data is
    jiterry (this is on an interlaced screen). After that everything works
    quite smoothly. I like V2.7 using the larger screen (interlace as the
    WB screen).

4229.4Maybe I/O relatedDECWET::DAVISYou always get what you deserveMon Nov 05 1990 11:367
    I've noticed that if you are viewing a large file MM continues
    accessing the disk while you are reading/scrolling.  Maybe the jitters
    are related to disk I/O and screen activity.  Like -.1 says, my first
    screen jumps a little but scrolls smoothly after that even with
    300-400K files.

4229.5Mouse Motion and JitterinessHKFINN::MACDONALDVAXELN - Realtime Software PubsTue Nov 06 1990 09:218
    The mystery remains. However, I was able to stop the jittery scroll and
    make it perfectly smooth, bu rapidly moving the mouse in a circular
    motion! Now, why would the mouse have an impact on the smoothness of
    the scroll. The mouse buttons are used to control the direction of
    scroll, by why a rapid circular motion would effect the smoothness of
    the scrolling is a mystery.
    
    Any suggestions? Hardware, software?

What mouse accelerator program are you using?  Turn off all your background
processes or boot from standard wb1.3 floppy and try it.

    FWIW, I am using Qmousev1.6 with the acceleration and threshold
    "increased".  I would try what -.1 suggests and see what happens.  Are
    you using an interlaced or non-interlaced MM screen?

    That was the first thing I thought of. Like I said earlier, V2.5 does
    not exhibit the jitters. I even tried it without the 2620 and other
    periphs, and on a virgin Workbench disk. That is why I suspect a
    problem with my version of the mother board - or Fat Agnes ...
    
4229.9CLO::COBURNGrowing older, but not up...Tue Nov 06 1990 14:538
    I use DMouse 1.? (2 i think) and MuchMore V2.7 seems to be pretty
    smooth when nothing much else is going on (PopUpMenu, SID and 2 CLIs -
    all quiet). 
    
    I can make it jitery by doing VIRTGIF or other CHIP memory eater runs
    on my 2000.

4229.10StackDICKNS::MACDONALDVAXELN - Realtime Software PubsTue Nov 06 1990 15:133
    I noticed that ARTM displays MuchMore V2.7's stack as a -38000 or so,
    while MuchMore V2.5 display a stack of 9000 or so. Does the negative
    value have any significance?
4229.11CLO::COBURNGrowing older, but not up...Tue Nov 06 1990 18:5111
    I just fired up ARTM and see a Stack of -149000+ with MuchMore.
    
    MuchMore must use a method of setting the stack that ARTM doesn't
    understand. 
    
    It still seemed smooth (even with JRCOMM running) on my interlaced
    display. I know these comments aren't helping you solve your problem
    Paul but hopefully if you get enough information you can find out what
    is different. Good Luck.
