11:16 Design #1615 (Rejected): apply: remove for RingHom
As done for CoCoALib, permit RINGHOMs to be applied directly to LIST and MAT.

22:42 Bug #1613: CRASH with RingHom from FrF
Actually a separate bug: @CommonDenom(a*x^2-1/a)@ gives 1 rather than @a@... Ooops!

09:52 Bug #1610 (Closed): IsInRadical: some more little bugs
I met some more bugs for extreme cases.
Usually, after isolating them, the solution is trivial.
List below.

John Abbott
22:35 Bug #1215 (Closed): RationalSolve: gives "Error: must be non-zero"
Closing this issue because there is no clear indication of what to test.
I suspect the new design of @RationalSolve@...

22:32 Bug #1537 (Closed): EmacUI: strange colours, sometimes
I have not seen the problem of unexpected colours for some time.
Reading through the notes suggests that Emacs's way...

@ApproxSolveTF@ was surprisingly fast on the example given in the description (about 9s, vs 64s using @ApproxSolve@).... John Abbott
20:34 Bug #1573: ApproxSolve: very imprecise
I have just updated the manual entry for @ApproxSolv@.
I wonder what @ApproxSolveTF@ does... mmm???

22:18 Bug #1539: Website: installation instructions for Microsoft
With luck the current instructions will be well tested over the next couple of weeks.
I hope we can close this issue...

CoCoALib and CoCoA-5 do often monitor for ctrl-C. Inside CoCoA-5 the situation seems to be reasonably good.

13:04 Bug #1573: ApproxSolve: very imprecise
My hack favours correctness over speed.
Is there a verbosity level which gives useful info? If so, document it (ri...
