@xisco: 

yes, you're right, i *hope* i found the source of the problem, 

i started this bug / thread just as an shorter approach to the problem, i'm in
doubt whether plenty people would invest the time and energy to read through
the other thread ... 

at this moment i can confirm that the problem is still present in ver.: 

Version: 6.3.0.0.alpha1+ (x64)
Build ID: 63b39fe87644587210214198fb67d6b3fb3343c5
CPU threads: 8; OS: Windows 6.1; UI render: default; VCL: win; 
TinderBox: Win-x86_64 at 42, Branch:master, Time: 2019-05-27_03:06:43
Locale: de-DE (de_DE); UI-Language: en-US
Calc: *unthreaded*, 

imho it is important to kill this out, but may be i'm the only user with a big
file using comments ... 

while i'm writing this my computer is busy for more than 30 minutes copying
four rows of very simple test data without any formula (in columns A:CH), but
with an comment - all the same - in about every tenth cell, to rows 1:12000.
'not responding', up to 25% percent of cpu load on a modern machine,
aggressively eating memory, fans on to medium ... there is something too
complicated with the representation and / or handling of comments, may be an
erroneous recursion? 

after the copying the complete area is kept marked and nothing - neither
mouseclick than cursor keys - produced 'workable effects' for the next hour,
just cpu load and fan noise. 

just check yourself. 

(maybe it's an occurence of #76324, unresolved in the buglist for more than 5
years now) 

(imho a comment is a very simple data structure, a string related to only one
cell, no formulas etc., such a thing shouldn't kill the program?)

whoever likes to risk the usability of his computer is invited to load the file
i'll provide with the next comment, save your other work beforehand! 

reg.
