             Bug #: 118546
        Issue Type: DEFECT
           Summary: CPU 100% on switched off AutoCalculate with
                    Conditional Formatting on date values
    Classification: Application
           Product: Spreadsheet
           Version: OOo 3.4 Beta
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical

         Component: ui
        AssignedTo: spreadsheet@openoffice.org

Created attachment 76926
  --> https://issues.apache.org/ooo/attachment.cgi?id=76926
reproduced problem in sample file

Problem description: When spreadsheet on foreground with switched off
AutoCalculate + there are some cells with Conditional Formatting and date
values, very high CPU load can be seen everlasting.

For simplicity I've created simple scenario (in reality I have complex document
and conditional formatting is only in the first column).

Steps to reproduce:
1. Create new Calc / Spreadsheet document
2. set A1 =TODAY()
3. set B1 .. K1 = A1+1 .. J1+1
4. copy row 1 to rows 2 ..40
5. set on this (A1..K40) cells the conditional formatting:
  [x] Condition 1: Cell value is equal to TODAY()
6. set Tools / Cell Content / [ ] AutoCalculate

Current behavior: very high CPU load: 30-100% without any user input

Expected behavior: minimal CPU load (0-1%)

Platform (if different from the browser): probably on all platforms (at least
on linux and windows). this bug is also in older versions (at least 2 years
ago)
