I checked in code to show why work is not being requested in a scheduler RPC.
There are actually quite a few cases:

case CANT_FETCH_WORK_NON_CPU_INTENSIVE:
return "non CPU intensive";
case CANT_FETCH_WORK_SUSPENDED_VIA_GUI:
return "suspended via Manager";(suspended project prevents any work requests)
case CANT_FETCH_WORK_MASTER_URL_FETCH_PENDING:
return "master URL fetch pending";
case CANT_FETCH_WORK_MIN_RPC_TIME:
return "scheduler RPC backoff";
case CANT_FETCH_WORK_DONT_REQUEST_MORE_WORK:
return "\"no new tasks\" requested via Manager";(work fetch has been suspended for this project)
case CANT_FETCH_WORK_DOWNLOAD_STALLED:
return "some download is stalled";
case CANT_FETCH_WORK_RESULT_SUSPENDED:
return "some task is suspended via Manager";(suspended tasks prevent more work requests from this project)
case CANT_FETCH_WORK_TOO_MANY_UPLOADS:
return "too many uploads in progress";
case CANT_FETCH_WORK_NOT_HIGHEST_PRIORITY:
return "project is not highest priority";(project is overworked - other active projects are due computing time)
case CANT_FETCH_WORK_DONT_NEED:
return "don't need";(the client work buffer is full).

Hi.

Anyone know what version for ubuntu has the menu redraw issues on Linux fixed, I've got 7.0.27 that came with 12.04lts.
It worked o.k. yesterday but this morning when i started Boinc up there is only part of the file menu showing so I can't do much with A.T.M. so what is the best way to go, should I just remove it & install an older one or is there a way to fix it.

Preliminary Change Log 7.0.28 --> 7.0.29:


MGR: Remove the visuals in the wizard for multi-core and opencl. This area will get a bunch of work in a future commit.
client: show <vbox_window> option in log, and give warning if include this while in sandbox mode.
MGR: Fix build breaks.
MGR: Fix menu redraw issue under Ubuntu's new interface. fixes #1180 (From Huibert)
MGR: Wait until there is valid data in the list box before processing the OnProjectSelected() event.
Fix for linux idle detection bug with USB mice.
client: if available, use GPU model name from CAL for OpenCL model name.
client: added the definitions for the new Windows 7/2008r2 preSP1 and Windows 8/2012 SKUs based on the winnt.h from the Windows 8 RC SKD (also added as proof).
client: added the detection for some more Windows SKU.
client: Updates provided by Teamwork of Planet3Dnow.de to coproc_detect.cpp added CAL_TARGET_ID 21 as : AMD Radeon HD 78x0 series (Pitcairn) (from [P3D] Crashtest).
client, GUI RPC: detect and export the PCI bus, device, and domain #s.
Mac installer: Fix bugs I introduced on May 3 and May 6.
Mac installer: Create or delete Login Items and set screensaver properly when installing for multiple users on OS 10.7, 10.8
