Hi!
We use tortoise 1.9.7 with zend studio 13.6 on Windows10 x64 (a eclipse based php IDE) and experience „locking problems“ since the update to 1.9.x.
When working via Tortoise we recently experience problems.
We see this kind of error only since updating tortoise svn to 1.9.x. from 1.8.x. using 1.8.12 doesnt show this problem.
We use zend studio and totoisesvn for years and it worked in the past with older versions, so actions at the same time with both tools were running smoothly.
