Thomas,
I have run into an issue after updating DataWarrior to the latest version when importing text files. When I import a text file that contains more than 500 rows, something happens with the SMILES data for each row. Many of the rows just display nothing where a structure should be present.
I have attached two text files, one with 500 rows and one with 501. The first file imports properly, while the second file has many empty structure cells.
For reference, I am using the 4.7.1 32-bit Windows installation, and I have previously imported larger files (3000 rows) without running into any similar issues.
As always, thanks for your work on this tool!
Andrew

Dear Andrew,
thank you very much for the detailed bug analysis and report. I have found and corrected the problem in the source code. With more than 500 rows SMILES parsing switches from single thread to a multi-thread approach. Unfortunately, a molecule buffer was erroneously shared by those threads leading to unpredictable results. Since this is a severe problem, I will release an update in the next days...
